DoQR-'sECUREFL SPECIFICATION forming part of Letters Patent No. 512,572, dated J' anuary 9, 1894.

Application iiled March 14l 1893. Serial No. 465,939. (No model.)

My invention relates to a door s ecurer, and

it has for its object to provideadevice of that character, which is adapted for use as an auxiliary fastening for doors opening inward, and the device is so constructed that it may be expeditiouslyand conveniently applied to any such door, 'and when placed in position the door can not possibly be opened from the outside unless it is forced from its hinges, particularly so when the device is employed in connection with other usual fastening devices, such as locks, bolts, dac.

In practice I prefer to combine .my improved securer with a pocket knife but any other suitable form of support may be employed. By combining a door securer with a pocket knife it is always at hand, and the fact that the device may be contained within a pocket knife without interfering with the blades, makes it evident that the device need not be very large or cumbersome.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

- Figure l is a plan view of the securer applied to a door to lock the same, the knife with 'which the device is connected being shown in transverse section. Fig. 2 is a side elevation of the knife and likewise aside elevation of the device, showing the latter in position for use. Fig. 3 is a 'rear view of the knife handle, showing one portion of the device in front elevation and the other portion in vertical section, the parts of the device being in the position shownin Figs. 1 and 2; and Fig. 4 is a rear elevation of the knife handle, illustrating the device as folded up therein; and Fig. 5 is a side view of the knife, illustrating the device also in its folded position.

In carrying out the invention, at one side of the knife handle A, at the back thereof a recess 10, is produced, which recess extends .longitudinally along the side of the handle,

being produced partially in the back and partially in the side, While the. inner end l0a of the said recess is made practically semi-circular, as shown in Figs. 2 and 5. The forward or outer end of the recess, designated as 10b, extends transversely across the back of the knife; thus the recess 10 may be said to be of essentially angular construction'. A second recess 11,v is produced diagonally in the back of the knife handle, as shown best in Figs. 3 and 4. The recess meets or joins 'a portion of the body section of the recess 10.

The deviceconsists of a clamping barBand a locking bar C, the clamping bar being located in the recess 10 and the locking bar in the recess 11. The locking baris shaped substantially as is the recess. Therefore the said bar is somewhat angular in cross section, and it comprises a body section 12, which extends along the body or straight portion of the recess'10, and a sharp spur 13, standing at a right angle from the body, which claw is adapted to enter the upper transverse section 10b of the recess, while at the lower or inner end`of the body of the clamping bar a head 14, is formed, of somewhat semi-circular construction,and the bar is pivoted at the head, the pivot pin extending into the back portion of the knife handle, The semi-circular head 14 of the clamping bar is located in the lower or semi-circular section 10iL of the recess 10.

'lhe clamping bar is adapted to be drawn outward when used, so that it will stand, as shown in Figs. 1 and 2, at aright angle to the knife handle, extending beyond the back thereof; and by reason of the semi-circular construction of the head of the clamping bar a shoulder 15, is formed at that point.l The body of the clamping bar may be and preferably is provided with a nail slot 16.

u The locking bar C, is pivoted at its center in the recess 11, and when the locking bar is contained within its recess it is practically smoothly located therein, andwhen brought into action the locking bar is turned so as to stand transversely across the back. At one side of one end of the locking bar a projec ICO tion 17, is formed, which is the only portion of the bar which extends beyond the back of the knife handle when the bar is contained within the recess, and this projection is provided in order that the bar may be readily turned bythe thumb of the hand holding the knife handle.

In the operation of the device, the clamping bar is drawn outward from the handle until it stands at a right angle to its back. The body of the bar is then brought in engagement with the door jamb D, as shown in Fig. 1, and the spur or claw 13 is made to slightly enter the jamb while the body of the bar extends transversely outward from or across the jamb, the knife back being near or practically in engagement with the inner face of the jamb. The doorD,is then closed, whereupon the door will force the claw 13 into the jamb the full length of the spur, and this action takes place while the door is being forced to the closed position; and at that time the clamping bar will be located between the door and the jamb. Next the locking bar is thrown downward until it engages with the shoulder 15 of the locking bar and extends transversely across the back of the knife and the said locking bar; one end of the locking bar will then be in front of the door, while the other end will be in front of the door jamb. It is evident that when the door securer is in this position it .will be utterly impossible for the door to be opened from the outside without being torn from its hinges, or otherwise broken, as the more tension that is brought to bear upon the outer face of the door, the rmer the device will hold the door in place; and as the device is contained within a pocket knife, and in no manner interferes with the action of the blades, as is obvious from the drawings, the device is always at `hand and is not liable to be forgotten, as a knife is apt to be often required and is generally carried.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. In a door securer, the combination with a support, of a clamping bar pivoted to one side of the same, and a locking bar pivoted upon the rear of the support at a point above the pivotal point of the clamping bar, whereby when the clamping bar is turned down the locking bar will engage the same and lock it, substantially as shown and described.

2. In a door securer, the combination with a support recessed at its side and back, of a clamping bar pivoted in the sid recess and provided with a projection near its pivotal point, and a locking bar pivoted in the back recess and adapted to engage the projection on the clamping bar, substantially as shown and described.

3. In a door securer, the combination with a support having an angular recess in its side and a recess in its back, of a clamping bar having a claw at one end and a projection at the other, and a locking bar adapted to be turned down and engage the projection on the clamping bar, substantially as shown and described.
